Application filed November 22, 1911. Serial No. 661,647.

To all whom it may concern Be it known that I, WILLIAM MEISCHKE- SMITH,a subject of the King of Great Britain, residing in London. England,(whose post-oflice address is The Asiatic Petroleum Company Limited, of24 and 28 St. Mary Axe, in the city of London, England,) civil engineer.have invented a certain new and useful Improved Machine for DeliveringMeasured Quantities of Liquids, of which the following is aspecification.

The invention relates to'machines for filling oil tins with a constantweight of oil, and applies more particularly to the arrangement by whicha number of these cans or tins is placed on a square support on aturn-table, so that all the tins on one side are filled at the same timeby nozzles connected to the separate compartments of a large container.It is important in practice that each tin should contain the samepredetermined weight of oil irrespective of the changes of density ofthe liquid due to temperature or other causes. For this purpose thevolume of the oil discharged from its oompartment into the respectivetins must vary according to the density, capacity of each compartmentmust be adjusted correspondingly, and for practical eiiiciency thischange of capacity should be effected simultaneously for all thecompartments. Arrangements have been proposed for altering the capacityof the compartment according to the specific gravity of the difierentliquids used as shown by an index, and plans have also been proposed toalter the capacity according to the temperature, when the same liquid isalways employed. ut no arrangement has hitherto been known in which thecapacity of the compartments can be adjusted for liquids of differentspecific gravities at varying temperatures by setting an index to thecorresponding graduation on a fixed scale. According to the presentinvention, when the density of the oil has been determined by apreliminary operation, the requisite change of capacity of eachcompartment is simultaneously effected by setting a hand to thegraduation of a dial corresponding to this density, and should anychange of temperature occur atfecting the density of the oil, thecapacitv change is effected by moving a second pointer connected to aspindle carrying both pointers to a graduation on the same dial that isthe effective corresponding to the temperature as shown by a thermometerimmersed in the liquid. The ad ustment is rapidly made simultaneouslyfor every compartment by simply observlng the thermometer and turning ahand wheel until the pointer connected to the hand wheel shaft bysuitable gearing is opposite the actual temperature at the time, asshown on the graduated dial. According to the invention also therotation of the shaft connected to the hand wheel adjusts slmultaneouslythe axial positions of the end plates of drums, one of which is fixed inevery compartment, so as to vary the capac1ty of these compartments asrequired. Also improved means are described of releaslng the air duringthe process of filling the compartments with oil and of lowering thenozzles and opening the discharge stop cocks when the compartments arebeing emptied.

Figure 1 isia part side elevation showing one compartment in section,Fig. 2 an end elevation of a machine constructed according to theinvention, Fig. 3 is a complete plan view to a reduced scale, Fig. 4shows one of the air release valves, Fig. 5 is a sectional elevation, toenlarged scale, of one of the compartment drums with an adjustable endplate, Fig. 6 is a sectional plan of a portion of the containing vessel,showing the compartment ofFig. 5, and Fig. 7 is an end elevationofa'part' of the compartment casmg and containing vessel.

In the figures, 1 represents the separate compartments of the containingvessel, 2 the cylindrical drum, whose capacity can be varied by theaxial displacement of the end plate 3, rigidly attached by the key 6 tothe shaft 4, which can be turned by the hand wheel 5, not shown in Fig.2. The end plate 3 has a screw thread on its outer circumferenceengaging with a screw thread on the inner circumference of the fixedcylinder 2. Small holes at the top of this fixed end allow the spacebetween the fixed and movable ends of the cylinders to be filled withthe oil. On the exterior of drum 2, a plurality of guide members 2having slotways 2 running parallel with the axis of the drum are fixedFigs. 57. A bolt 7, having a threaded portion screwable in a boss 1 onthe side of the compartment 1. is adapted to be turned so that itsterminal point may enter or be withdrawn from the I slot of one or otherof the guides when brought into register with it. When the point of bolt7 engages a slot 2 the drum is held fast, but when the point iswithdrawn, the drum is free to be rotated by hand through a hand holeprovided with a cover 8. When it is required to adjust the capacity ofany compartment independently of the others, the associated bolt 7 isreleased and the cylinder 2 rotated by hand through the hand hole andagain fixed by means of bolt 7. To the cover 8 a piece of hard wood isattached; by reducing, or if necessary en tirely removing, this piece,the capacity of the compartment may be considerably increased whenrequired. By the means described the capacity of each compartment of themachine may in the ordinary construction be varied so as to deliver thesame weight of oil for any specific gravity between the limits of .7 8and .85, but this range can be varied in the construction of the machineto suit special requirements. It is obvious that other equivalentdevices for displacing the movable end of the cylinder may besubstituted for the screw threads shown by way of example.

The shaft 1 is connected by the reducing gear 9 to the spindle 12 whichcarries the two pointers 10 and 11. Both pointers move over a dial 14provided with two scales 14', 14 the one graduated in terms of density,the other in degrees of temperature. In adjusting the capacity of eachcompartment, the density of the oil is determined in the ordinary way bydrawing off a small quantity by a stop cock 38 provided on the reservoir38 for this purpose; the hand wheel 5 is then turned until the pointer10 is opposite the graduation showing this density on the density scale11' of the dial 14. The temperature of the oil is then read off from athermometer. preferably of the circular form with dial 38, immersed 1nthe reservoir at a position where it can be readily seen by an operatorat the hand wheel 5. The hand 11 which is loose on the spindle is thenturned until it is opposite the graduation corresponding to the actualtemperature on the scale 14 on the dial 14 and clamped in this positionby the milled nut 13. The temperature scale is graduated so that theindications represent the changes of density corresponding to thechanges of temperature. Should the temperature vary at any time afterthe hands have been set as described, the operator has only to adjustthe hand 11 to the temperature, as shown by the immersed thermometer bymeans of the hand wheel 5 and the shaft 4 will also be turned with thespindle 12 so as to adjust the volume of the cylinder in eachcompartment as required to deliver the required weight of oil into thetins when the compartments are emptied. The hand 10 points always bythis device to the density of the liquid under the existing conditions.The shaft 4 is supported in bearings, where it passes through thedividing Walls of the compartments and at the end compartment nearesttothe hand wheel 5 is packed so as to be 011 tight by means of thestuffing box and gland 15.

Oil is admitted to the compartments from a reservoir 38 through a mainvalve in the valve casing 16, which is opened and closed by the spindle17 turned by the hand wheel 18. An air vessel 39 is attached to thereservoir to absorb any shocks on openmg or closing the main valve.WVhen the main valve is opened, oil flows into the central chamber andwhen this is filled flows lnto the adjacent chambers on either sidethrough the semi-circular spaces 19 provided as shown at the top of thejunction of two ad acent compartments. Air escape valves 20 (Figs. 1 and4) are provided at the top of the end compartments. The valves areweighted so as to remain open against the escaping air but so as toclose under the flow of oil which occurs when the compartments are allfilled and the oil reaches the level of the valves. The weights tendingto keep the valves open can be adjusted depending upon the head orpressure at which the oil is admitted, so as to minimize the amount ofoil escaping by the overflow pipe 40. When the weights on the valves areseen to rise, the main valve 16 is closed by the hand wheel 18. Thelever 21 is then pulled 'down to open by means of the common sliding bar23 the air stop cocks 22 fitted to each compartment, which release anyair confined in the spaces 19. The lever 21 in its lowest position liesin the path of the handle of the valve wheel 18 and prevents the wheelfrom being turned and the main valve 16 opened at the wrong time.

Vhen the compartments have been filled the hand wheel 24 is turned so asto move the sliding bar 25 to the right by means of the screwed rod 26,so as to lower the nozzles 27 into the tins placed below them. Thesenozzles are pulled down by weights 28 and the attached sleeves 29 slideover the pipes leading from the compartments. Projecting pins 32 on thesliding bar 25 press against the arms 31 of the two-armed levers. \Vhenthe bar is moved to the left, the arm 30 of these levers is raised andby means of the rollers 33 lifts the bar 31, which raises the nozzles bythe collars 35. When the sliding bar 25 is moved to the right, theweights attached to the nozzles cause the bar 34 to fall into the lowerposition, in which the nozzles are placed in the tins. In this positionthe slotted links 35 are moved by the pins 36 attached to the slidingbar 25 so as to open the stop cocks 37 on the discharge pipes of thecompartments.

When the contents of the compartments have been emptied into the tins,the hand wheel 24 is turned in the opposite direction, the nozzles areraised, and the cocks shut.

In the construction of the machine shown, there are nine compartments,each compartment holding lbs. of oil, but the number and capacity of thecompartments can obviously be varied as may be required for any specificpurpose.
